Garmin Female Quarter Turn Mount to Modular Mounting System 3 Prong Adapter (GoPro Mount)

thingiverse

What I use this part for is to attach various lights under my Garmin Edge mount, which has a "male" mount on the bottom, as seen on the picture. I cut up and attached together the two remixed parts with FreeCAD, so the credit mostly goes to the original designers of both parts, really neatly done, thanks! Use an M5x25 bolt and the "Knob_v5.stl" to secure parts to it.
